No i hope i really understood you this time, you should do something like this.

pawn Код:

new chasecar;//Global variable in the top of your script!

public OnGameModeInit()
{
    chasecar = CreateVehicle(411,x,y,z,angle,3,3);//here i used the variable and created an infernus for example
    return 1;
}

//Later OnPlayerCommandReceived
{
if(IsPlayerInVehicle(playerid, chasecar)) return SendClientMessage(playerid,RED,"Commands are disabled in carchase!");
}
